ASSSplitContext* ff_ass_split ( const char *  buf  ) 

Split a full ASS file or a ASS header from a string buffer and store the split structure in a newly allocated context.

Parameters:
buf String containing the ASS formated data.
Returns:
Newly allocated struct containing split data.

ASSDialog* ff_ass_split_dialog ( ASSSplitContext ctx,

Split one or several ASS "Dialogue" lines from a string buffer and store them in a already initialized context.

Parameters:
ctx Context previously initialized by ff_ass_split().
buf String containing the ASS "Dialogue" lines.
cache Set to 1 to keep all the previously split ASSDialog in the context, or set to 0 to free all the previously split ASSDialog.
number If not NULL, the pointed integer will be set to the number of split ASSDialog.
Returns:
Pointer to the first split ASSDialog.

)

Split override codes out of a ASS "Dialogue" Text field.

Parameters:
callbacks Set of callback functions called for each override code encountered.
priv Opaque pointer passed to the callback functions.
buf The ASS "Dialogue" Text field to split.
Returns:
>= 0 on success otherwise an error code <0
